Not all devices have such a signature in the first place. The US Navy

generally have no significant signatures either. TRF radios lack
oscillators, hence have no significant EMI/RFI signature.


The only TRF radio I ever owned certainly had an oscillator. Matter of
fact, it had two, one in the mixer stage and one BFO.


Except that by definition, a TRF cannot have a mixer stage, it has no
IF stages. that why it is called a TRF.


I'll take your word for it, but when I learned the term it only seemed
to mean a radio with a tuned RF stage, implying nothing more about the
radio. Kinda had the sense of "air-conditioned car".

No wonder twelve years of inspections found NOTHING.
